The evolutionary and ecological role of heat shock proteins
It is suggested that the expression level of Hsp in each species and population is a balance between benefits and costs, i.e. a negative impact on growth, development rate and fertility as a result of overexpression of Hsps. Expand
Adaptation of Drosophila to temperature extremes: bringing together quantitative and molecular approaches
The way the Drosophila research has been used to understand the evolution of plastic responses, tradeoffs and limits to selection, and to develop links between laboratory studies and adaptive shifts leading to population and species differences is examined. Expand
Conservation Genetics
• Richard Frankham’s (1995) review argued species with low variation would have “reduced ability to cope with environmental change during evolution, and so have shorter evolutionary lifespans.” HisExpand
Mitochondrial DNA Variability in Italian and East European Wolves: Detecting the Consequences of Small Population Size and Hybridization
The observed mtDNA monomorphism is the possible outcome of random drift in the declining and isolated Italian wolfpopulation, which probably existed at low effective population size during the last 100- 150 years. Expand
Genomic signatures of local directional selection in a high gene flow marine organism; the Atlantic cod (Gadus morhua)
Findings illustrate that adaptive population divergence may indeed be prevalent despite seemingly high levels of gene flow, as found in most marine fishes and have important implications for the understanding of the interplay of evolutionary forces in general, and for the conservation of marine biodiversity under rapidly increasing evolutionary pressure from climate and fisheries induced changes in local environments.

Marine landscapes and population genetic structure of herring (Clupea harengus L.) in the Baltic Sea
Application of a novel method for detecting barriers to gene flow by combining geographical coordinates and genetic differentiation allowed us to identify two zones of lowered gene flow that were concordant with the separation of the Baltic Sea into major basins, with environmental gradients and with differences in migration behaviour.

Upper thermal limits of Drosophila are linked to species distributions and strongly constrained phylogenetically
It is suggested that this group of insects is unlikely to buffer global change effects through marked evolutionary changes, highlighting the importance of facilitating range shifts for maintaining biodiversity. Expand
Correlated responses to selection for stress resistance and longevity in a laboratory population of Drosophila melanogaster
The results indicate a possibility of different multiple‐stress‐resistance mechanisms for the examined traits and fitness costs associated with stress resistance and longevity. Expand
Microsatellites provide insight into contrasting mating patterns in arribada vs. non‐arribada olive ridley sea turtle rookeries
The results suggest that the differences observed in levels of MP between arribada and solitary rookeries are due to an effect of abundance of individuals on the mating system, supported by a regression analysis combining other paternity studies on sea turtles which shows that levels ofMP increase with increasing abundance of nesting females.

Conservation genetics in transition to conservation genomics.
This work focuses on how the transition of conservation genetics to conservation genomics leads to insights into the dynamics of selectively important variation and its interaction with environmental conditions, and into the mechanisms behind this interaction. Expand
